Application filed July 13, 1909. Serial No. 507,361.

To all whom it may concern: I i

' Be it known that I, RYDOLIII R. GUEN- 'rnnn, J12, a citizen of the United States, residing at South Bethlehem, in'the' county 5 of Northampton and State of Pennsylvania,

have invented a new and useful Signaling Device, ofwhieh the following isa specification. Y

The object of this invention is to provide a simple and efficient device more particularly for use on motor vehicles by which, should the speed of the vehicle exceed a predetermined limit, an alarm will be sound ed so that the operator of the vehicle willjwhichwill occupy very little room on the 7 vehicle and W111 be out of the way of the driving mechanism or of the occupants of the vehicle. 7

These objects and such other objects willhereinafter incidentally appear are attained by the use of the apparatus illustrated in the accompanying drawings, and the in-' vention consists in certain novel features thereof, as will be hereinafter first fully described and then particularly pointed out in the drawings referred to, Figure 1. is a bottom plan view of so much of an automobile as necessary to illustrate my invention. Fig. 2 is an elevation of the same vibratoriy beater. Figs. 4 and 5 are detail views the tappet for actuating the said 'tion, it being understood that my improved signal may be applied to any vehicle which is; apt; to be driven at a high speed, and may also be applied to some forms of machinery times attained.

e In applyingmy invention to any auto mobile the driving axle 1 is provided with a sprocket wheel 2 by which the motion given the axle from the driving Wheels will be imparted to the signal through the nicchanisrn to be described. Mountedin suitable brackets 3 as a counter shaft. 4:, on one end of which is a detail view of a part of the,

in which a dangerous speed issomevehicle is lnoving at a; low rate of speed.

is fixed a sprocket pinion 5,-conneeted to the sprocket wheel by a chain (3, as clearly shown Upon the counter shaft 4 I mount a governor T which is of the centrifugal type, and has a fixed collar 8 secured to the shaft atone end, a slida'ble collar or sleeve 5) mounted on the shaft at the other end, and spring arms 10 secured to and con neetiug the said collar and slidable sleeve. At the, centers of the said spring arms 10 i provide the w ights 11 which will be thrown centrifugal force when a high speed is imparted to the shaft,-as will be readily understood, and these weights 1]. are in the form of boxes hav ng tappets 12 seatedin and projecting; through the same,

the Stiltl tappets carrying pinstil playing within the boxes and adapted to impinge against the front of the boxes so as to prevent the pins flying from the same. Springs 11 are seated in the boxes and bear against the tappets so as to hold them nor I molly-against the front walls of the boxes.

as will be readily understood on reference to Figs. 1 and Depending from the body of the vehicle at'ljacent to the brackets 3 are a pair of brackets 15 in the lower ends of winch a rod 16 19 secured. At the center of the said rod 16 a vibratory beater 17 is mounted, and the saidbeater is connected with the rod-1G. by incans of a spring 18 coiled around the rod within the heater and having its opposite ends secured to the rod and the beater respectively. This beater, as clearly shown in Fig. 2, has an upstanding arm 19 carrying a head 20 at its upper end and a lowe' arm 21 which extends to ward the governoraiul is arranged in such position that it will project into the path of the tappets when the governor is expanded under a high rate of speed, as will be understood. Adjacent the heater, and with its front end in the path of movement I of thehead 20 of the heater is a horn 22 on the under-side of the vehicle.

fit)

having' a diaphragm stretched over its smaller end so that when the beater is vibrat ed, the head of the same wlll play upon said diaphragm, andconsequently produce a loud drumming sound.

' The. operation of the device will, it thought, be readily understood. When the the'parts will assume the positions shown in Fig. 1 and in full lines in Fig. 2.- Should ltlfi iio the speed of the vehicle increase to an unsa'le extent or beyond a limit which may be predetermined by giving the proper resisting strength to the spring arms of the governor, the centrifugal action of the governor will throw the weights 11 outward so that the tappets will assume the position shown in dotted lines in Fig, 2, and conse-' quently as the governor continues to revolve will strike upon the end of the arm 21 of the heater and depress the same to the position shown in dotted lines in Fig. 2, from which position the beater will be returned by the action ofthe spring; 18 immediately after the tappet has cleared the end of the beater arm 21. This return movement of the beater will throw the head 20 against the diaphragm on the end of the horn and will thereby sound the alarm. The liability of the parts to bind is effectually overcome by theprovision of the springs Pt and 18, the" spring 18 servingto yieldingly hold the beater upon the rod 16 and the springs let permitting the tappets to readily yield to the impact upon the beater arm so that they may recede as they are moved pastthe beater by the governor.

The device is very simple and may be applied to any vehicle and while the construction illustrated is the preferred embodiment of the invention, I do notlimit myself to the exact details shown. For instance, the

tappets may be arranged to ride upon the inner surface of a ring supported by thevehicle and connected with one pole of an electric battery, the other pole of the battery being connected to the spring arms of the governor. When the tappets are thrown out against the ring, a circuit will be closed through the, battery and, as a result, coils will be energized so as to impart the desired vibratory movementto the beater.

In l I have shown an automatic stoppingmechanism which may be employed in connection with the alarm, the vehicle being driven by an electric motor 23, mounted on the axle 1 in this instance.- Tlns stopping mechanism comprises a plug,-

Q, secured to the slidablefsleeve 9 and insulated from sa d, sleeve and the governor shaft. When the vehicle 1s proceeding at a slow speed, the plug 2% will fit between and in contact with brushes or terminals,,25, carriedby poles or arms, 26, which are secured upon the bottom of the vehicle body; and separated by a wooden'blockor other insulating material, 27. With the'plug in contact with the brushes, a circuit will be closed over the conductors, 27, leading from the poles 26, through the motor and a. bat-- 28 so that the motor will operate. vJhen excessive speed causes the sleeve 9 vice, of a vibratory beater arranged to pla the plug, of course, resumes its position be-' tween. the brushes and again closes the circuit.

lVhen the device is applied to a vehicle driven by a fluid pressure or explosive englue, a disk 29 is secured to the end of the plug and arranged to bedrawn against a valve (not shown) when thespeed is excessive. The said valve w1l l be arranged to permit escape of the steam or other driving agent in a thud pressure engine or to cut'.

or? the supply of fuel to an explosive engine until the speed has been reduced.

Having thus described my invention,what I claim is 1. A high speed alarm comprising a sounding device, a; vibratory arm adapted to play upon said sounding device, a governor arranged adjacent to. the vibratory arm, means for operating the governor.

2. The combination of a sounding device having a diaphragm, a beater arranged to play upon said diaphragm, and a governor carrying tappets adapted to actuate said heater. 1

3. The combination of a sounding device, a vibrator beater arranged to lay upon said sounding device, a centrifu a and yieldable tappets carried y said governor and adapted to impinge .upon saidvibratory beaten v I 4-. The combination of a sounding device,

cured to the governor, tappet arms mounted in and projecting from the boxes, pins in said arms 'ada ted to bear against the front walls of the ones, and springs seated between therear walls of the boxes and the saidarms.""- f 5. The combination with a sounding de upon the same, a governor, tap ets earrie by said governor. and arrange to enga the said heater and move the same from t e sounding device, and'yieldable means for governor,

and

, a heater arranged toplay upon the same, a

holding the said heater against the sounding device.

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature in the presence of two witnesses.
